Application filed November 9, 1917, Serial 110.201,059.y Renewed December 8, 1928.

My invention relates to improvements in cameras and to the light controlling devices of the lens therefor, and has for its objects, first, the automatic vsetting of the diaphragm, shutter, and focal distance, vseparately or in combination, second, the setting of the same singly or together by the simpleprocess of drawing out the lens supf porting the front, and, third, auxiliary lo means of settiufr the focus scale when the camera is closed; thev primary object being to obviate the requirement of skill or special knowledge on the part of the operator as to the proper or required settin of dia- I5 phragm, shutter and for focus', -1n taking pictures, but to provide means whereby ar- -itrary settings of either of 'said features may be made at will, and to provide means whereby when the camera is closed, the diaphragm, shutter and the focus scale shall be automatically reset to normal position, and shall automatically reset to proper position for taking the picture upon the reopening of the came-ra.

It will be noted in 'the drawings that thel camera bellows has been omitted for purposes of illustration, and that certain num.- bers used in the drawings and specification to indicate positions of setting/of the diaphragm, shutter, and focus, do not occur las, reference indications for parts.

In Fig. 1, the diaphragm andshutter scale, l'

shown in Fig. 17 has been omitted for purpose of illustration of action. The reference numeral 1 represents the cameracasing, supplied with the ordinary rigid or folding position as hed 3, hinged. if folding` as at 5, and supporting the ordinary track 7 adapted to slidably receive a carriage 9 having upright members 11. 13, slidably supporting a lens board or l'rout 14, having any elevating means. such as 17 indicating a nut on a threaded post l1. and a catch as indicated at 18 to hold said lens board in normal is usual in certain styles of canieras. as in Figs. 1, 2. 3, 4, 21, or having a rigid lens board or support 19 carried by a carriage. 20, as in Figures 18 and 19. The carriage 9 supports a horizontal cross slide bed piece 21, to which are secured the uprights 11, 13. the bed piece 21 being held iu normal central position by any efficient ordinary catch device represented h v the usual lever and knob binder 22.

n order to assure the normal central position of the lens board 14, two lugs 24, 2G are secured to and extend beyond the side thereof, and are adapted to enter a lock or centralizing slot-27, 28 formed in plates 29, 30, secured at opposite sides on the inside of the frame 1, as at 31, Figs. 1 and 2, the

said plate being offset from the frame surface as at 32, 33, as the lens front cannot be completely moved into the camera box or frame until the lens board is adjusted to central position vertically and horizontally, by the entrance ofthe said lugs in their respective slots. This device assures the centralizing of the lens board before the camera can be closed. 0n top of the cross slide 21, Figs 1, 2, 4, and 29, is a saddle or binder plate 34 which at the sides 35, 36 overlaps the slide 21. The said binder occupies a fixed position over the slide 21, and does not slide with the latter. At one end provide this binder with upwardly turned portions 37, 38 and holes 39 adapted to receive a pin or stud 40- serving as a fulcrum to a lever 41, which lever extends above the stud and is shaped as at 42, and downwardly through an opening 43 formed in the binder plate 34 and slide 21, and below the latter, as at 44, Where it passes between the ins 46, 47 secured in a slide bar 48 Whic isshaped as shown in Figs. 24, 29 and is slidably fitted in slots formed in the opprosite sides of the carriage 9, asfshown in igs. 1, 3 and 23.

To the under side of carriage 9 is pivoted at 49 a lever 51 having at its free end a pin and preferably a roller thereon 52 (Figs. 1, 3, 21, 23). Also to the under side of said carriage is pivoted at 53 small lever 54, having at its free end a pin fitted preferably with a roller 55. An adjusting screw 56 threaded in the side of the carriage bears at its inner'end against 'the lever 54 or the said adjusting screw may be threaded into the lever 54, as at 57, and bear against the i inside of the carriage side (Figs. 22, 23). A

Wire or other suitable spring 58 surrounds of this actuating plate. i-n which the platev 62 is pivoted as indicated at 63 and at its other end is provided with a slightly elonp gated opening 65 adapted to looselyT receive a pin 6G secured to the bed 3, Figs. 19, 21, 23. to limit the movement of the said plato.

The bar 48 slidable through and under the carriage 9 (Figs. 1, 2,23, 24) has an angular portion 67, and a slot 68, into which slot fits and moves the pin or roller 52 of the lever 51. The actuating lever 62 is ol'set upwardly slightly as indicated at 69 (Figs. 3 and'21). in order that it may pass freely over the focus scale device shown therein. disposed transversely thereto, and which will be described later. Integral with or firmly secured to the top ot the lever 62 by any suitable means, as indicated at 70, is a step or cam plate 71, provided on its right or one edge with a series of graded steps 72, the said steps being of gradually increasing Width and corresponding in longitudinal distances and proportionate relativedength to the position and proportionate length of the spaces of focal distances indicated on the respective focal scale. The opposite edge of the 'cam plate may. be provided with projections as at 73, disposed opposite certain of the aforesaid steps representing closely disposed focal distance indications. such as opposite the small space between 100 ft. and 59 ft.-25 ft. and 15 ft. and 12 ft. and 10 ft. of the focal scale of Fig. 21 and between 100 ft. and 25 ft. of the abridged focal scale of Fig. 19.

It will be seen that when the carriage is brought forward to focal position, the roller 52 of the lever 51 will strike against the angular or curved end at 74 of the edge 72 of the cam plate 71, and will be moved to the right, and thereby move the cross bar 48, and the lever 41 a distance proportional to the forward and sidewise movement of the roller 52 along the steps 72 of the said cam plate, and that as the carriage 9 or 20 comes to rest against the desired focal stop. the roller 52 will have come to rest against the step of the cam plate 71 corresponding to the desired focal distance indicated on the focal scale, and that the lever 51 will have been set at an angle corresponding to the relative position of the step on the cam plate on which the roller 52 rests. To facilitate the action of the roller 52 on tbe steps 72, the said steps effecting said roller 52 are glided into or angu'lally inclined to 'one an- -itl so that the diaphragm indexing and setting device will he, moved to index positionsl corresponding to the respective steps on the edge 72` of the cam plate 7l'` that. the roller 52 tomes to rest upon. In Fig. 21 the focal scale isl graded as shown from 10() to(i ti. and to the corresponding meters. and the cam plate 71 isfmarked with indications showing the relation that the indications ofthe focal scale bear respectively to the steps of the cam plate, and to the diaphragm openings, which latter are also indicated as on vthe diaphragm and shutter scales, in Figs.

1, and 17 and 18. In the simpler' camera shown in Figs. 18, 19 andv 20 but three focal' steps are shown andv three corresponding cam steps 72. In Fig. 21 it will be seen that 100 ft. of the focal scale corresponds to a cam step marked 100-16, i. e. 100 ft.- :#16 diaphragm opening; 50425 ft. corresponds to the cam step marked 50425=:#:16+; 15 ft.

corresponds to :#8; 12-10 ft. corresponds to 12-10=#8+; 8 ft. corresponds to 8:#4; and 6 ft. corresponds to 6:#4+. In Figs. 19 and 20 100 ft. corresponds to #16 diaphragm; 25 ft. to #8, and 8 tt. to #4. These relative proportions may, of course, be differently established and set. Assuming that the lens support carriage 9 or 2O is moved forward until the focal indexing 76v (Figs. 21and 22) and 77 (Figs. 18 and 19) comes to rest at 100 ft. of the focal scale, the pin or roller 52 will glide against the angular or curved edge 74+ of the cam plate v71.` and cause the lever 51 to be deflected to move the lever 41, 42 or 74, 75 to such a position as will set the diaphragm index device to #1G of the diaphragm index plate. It will he borne in mind thatone of the objects ot this invention is for the purpose of the diaphragm automatically setting to proper snap shot positions, and since neither stop :#128, #64. or #32 is ordinarily usable for snap shot exposures but is -used almost ex-` clnsively for time exposures, the Said actuating levers and stop index device standing normally at stop index #128 or 64, moves at once from such normal time stop position to #16 stop, the smallest stop usually used for snap shot exposures. If the carriage 9 is brought forward `to ft. of the focal scale, a compound actuating action takes place as follows: The cam ste i marked 50- 25:#16-iis preferably laterally disposed only a half step` and the half step projection 73 opposite said step on the opposite sido of the caln plate 71 by virtue ot the roller 55 carried b v the carriage 9 gliding against it and thereby forcing to 'the right. the said cani plate the distanceof a half step` the lever 41, 42 (or 74-75) is given a full step movenient. 'lhc adjusting screw 56 adjusts the roller to effect thel proper movement and to compemate for slack and wear. A silnilar action takes place at 50:#16+, 15: #8. and 1t):#8+ as shown in Fig. 21, and at 25:#8 in Fig. 19. The objet of this ation is to divide and lessen by onellalf the space or measurement. of a full step lmovement. and to half the angle of thesame in the glide of the roller 52 from one step to another where the steps are short due to the short interval between certain of the distances on thefocal scale and the correspondingr t'ocal lens positions.

In Figs. 18 and 19 the roller 52 is attached directly to the heel of the lever 74 in any suitable manner, such as by pin 78 rivetedjn a turned over portion 79, and the cam plate 71 is preferably curved as shown in Fig.`18 to the radius described by the said roller. On the lens support or on the carriage of Figs. 18, 19 is secured or formed a projecting nger pull device 80 curved slightly ont- Wardly as shown inF ig. 19, and. a corresponding one 81 is carried on the opposite side of said lens front or support and has a ,shank 82 passing loosely through a slot as indicated at 83, which shank is attached by a screw or otherwise to the lever 74 at 84,

and is preferably provided with graded steps 85 corresponding to the lever position of the diaphragm stops, the slot 82 being of suficient width to allow the raising of the tinger pull piece 81 during the drawing outof the lens support, to allow it to be forced in to cause either of the steps 85 to come to rest against the lower edge of the slot 88. In this connection, instead` of the lower end of the lever 74 terminating in a pin or roller 52, it may have a plane or square end or edge 86 (Fig. 20), and the cam plate may be formed as shown into square steps, the lateral surfaces of the steps representing the focal distances and the longitudinal surfaces representing the diaphragm stop openings and indications as shown. This square step cam plate 8-7 maybe securely fastened to the lens support camera bed, and the point 86 of the lever 74 may be caused to set against it-.by the movement of setting of the finger pull piece 81 to move the lever 74 to the various diaphragm stop positions and the shank 82 thereof may or may not abe pro vided with the steps 85. The journal 88 of this lever 74 is preferably placed in the center of the lens support or carriage. It will thus be seen that the action of setting the diaphragm to any one of the different positions and apertures will, by this means, also determine and set the lens support (and carriage) to the corresponding focal position, the relation between light and distance being generally constant in that light quantity is proportional to increased area and distance, light quantity, therefore, being, in general, proportional to focal distance, and that by employing the devices shown, either the moving of the lens support tofocal position sets the diaphragm to corresponding and appropriate index number and aperture, or, conversely, the setting of the diaphragm to desired position and aperture determines the corresponding focal position of the lens support and its lens. In Figs. 1 and 3 is shown the form of focus scale 89 having a slot 90 and index stop device 91 as usually employed in this type of camera. Any focus scale devicemay be employed in connection with my invention, but iii-Figs. 18, 19, 20 and 21, 1 have illustrated a preferred form of focal scale device, which consists of a plate 92, disposed at right angles to the track 7, and passing through slots formed in saidtrack, which slots may serve as guides to the movement of said plate 92. At one end of said plate 93 are cut steps corresponding to the various Ifocal distances at which the lens support is to be arrested. A stop device, Figs. 18 and 19, consisting of a plate 94; having a slot 95 and a screw 96 to clamp it in proper focal position to the carriage, is provided with a tooth or lug 77 adapted to move against thefocal scale steps (tooth 76 iin Figs. 21, 22). This' plate 92 may have a linger pull device as shown by the upturned part 97 and a pin 98 projecting downwardly into indentations 99 formed in the upper surface of a plate 101, secured to the camera bed, and adapted to be moved to the various positions and held by the spring contact of said pin and indentations.v In Figs. 21, 22, is shown a larger focal scale device, in which the plate 92 is widened at 102, and may be held in normal position by a spring 103 secured as at 104 to the camera bed. The opposite end of this plate 92 may he shaped as described at 97, but a pin 105 secured in said focal plate projects downwardly freely into the path of the steps 106 formed in a cam plate 107 held slidably by a retainer and guide 108 and screw 109 in a slot 110 in plate 107. A finger knob or projection 111 may project upwardly from said plate and downwardly through a. slot formed in the bed 3, as indicated by the dotted lines 112, (Fi 21, 22), .to enable the setting of the, foca device from the outside of the folding bed or door, when the latter is folded or closed. The cam plate 107 has an upturned portion 113, adapted to slidably receive in a hole a rod 114, having a head 115. On this rod. 114 is placed a wire spring 116 which bears against the portion 113 of plate A107 andv against a lug 117, through a hole in which lug the rod 114 slides. Securely fastened to the lug 117 is the wall or tubular portion 118 of a lexihle cable '125, shown broken and then continuing into the camera case'as at 1,19, upwardly at 120, across the underside of the upper part of the camera frame or case as shown by the dott-ed lines 121, either below said frame as at 122, or bedded therein as indicated at 122 (see Figs. 1. 21, 25 and 27) and-then downwardly as shown by the dotted osition 123 to a retaining clamp or holder 1ndicated at 124 which attaches it to the inside of the camera case 1. The iexible cable 125 (whose tube 118 may be made rigid through-l out most of the portion thereof contained in the camera casing, and then fieXible from the lower portion 120'to 117) is securely fast-- ened to the end of the slidable rod 114 at 126 its opposite end 127 being secured to the turned over portion 129 of a member 139, which member is slidably secured to the outside of a plate 131 having an elongated slot 132 which has indentations or catch devices, as shown at 133 on one edge of said slot.. These catch devices correspond in proportional distances apartto the proportional distances apart of the steps 106 of the side cam focal adjusting plate 107, which steps 106 in turn correspond to the increasing d1stances and position of the focal stop steps 93 of the focal plate 92. T he distances apart of the catch members 133 are proportional to and correspond with the distances apart of the index numbers of feet and metres of the focal vindex scale indicated on plate 131, which is preferably as shown recessed in the camera side frame 1. The shank of screw or rivet 134 passes through the slot 132 and is secured to the slidable member 130 to hold the latter in position in its relation to the plate 131. The endof a spring 135, as at 135, connects in a hole formed in the under side of a button 136, the shank of which button passes also through the slot 132 and is secured to lthe member 130 (Figs. 25 and 26). The spring loops around the shank of the rivet 134, itsfree endpressing against the straight side, as at 137, of the slot 132. The diameter of the shank of rivet 134 with its spring looped around it is vof a size small enough to freely slide in slot 132, and as the catch pin 138, which projects into and engafes the catch members 133, fand which is held normally in catch position bythe l members 133 that it may be in engagement v117.0f the camera bed.

with, from any catch and index position it may occupy below the normal top position in which the button 136 is shown, thereby permitting the return ofthe button 136 to 4such normal position by the tension exerted by the spring 116 against the portion 113 of the cam plate 5107, and t-he lug or journal The smooth lane edge 139 of said cam plate 107, by gliding against the pin' 105 of the focal scale device 92, returns it to normal position. It can readily be seen that if the button 1 36, which is provided with index-pointers 140, 141, on its opposite sides'to indicate the numbers on the focal index scale, is moved downwardl until its pin 138 comes in engagement wit the required catch members 133 of the focal index scale, the pull on the flexible wire 125..

will cause the setting of the focal scale device, either when the camera bed or door 3 is closed or open. 141 indicates the focal index scale usually supplied and secured to the bed or door of the camera illustrated in Figs. 1, 3, 21 and 22. This scale has an under fixed index plate 142 for sensitive plate exposure, and a,hinged index plate 143 for sensitive roll film exposure, hinged as at 144 and adapted to be turned back as shown in Fig. 22, when sensitive plates are employed. In employing such a (or any visible) focal index scale 141 on the camera bed in connection-with the focal plate 92, I

set the said .focal index scale farther away from the track 7, so as to allow a free space 145 for the travel of the lug-76 of the carriage 9 against the steps 93 of the plate 92,

' the surface of the plates 142, 143 being plane and without the catch indentations or movable stop, such^ as are shown at 90 and 91,

i, Figs. 1 and '3.

But 'the index numbers for vdistances can, of course, ybe marked on the focal plate 92, adjacent their respective steps 93, as shown in Fig. 19, and the index plate 142, 143, 144 be dispensed with.

In Fig. 3 is shown an open cam plate 145 which is adapted to connect as at 146 in the manner described regarding the flexible cable 118, 125. As modified meansof moving the focal plate 92, a bell crank 147 pivoted as indicated at 148, and engaging by a pin and slot 149 the focal plate`92 is adapted to con-4 'neet through a rod 150 movably secured to it by a pin as indicated at 151 with the iiexible cable 118, 125 at 1 46, in the manner heretofore stated. At the top of Figs. 1 and 25 indexand setting devices for diaphragm and i noJ shutter are shown. These devices, although shown in double column, are similar in all respects 'mechanically to the one described 'concerning the focal distancesetting scale, consisting of like buttons, connections and flexible cables, a point of difference concernthe camera case when the cairiage and lens support 9, 14 is moved out or in. These two cablesare indicated in partially folded position in the bottom of the camera casing in Fig. 21, in which the forward part of the i cable marked 152 leading from the button 153 ofthe'shutter setting 4device (Fig. 25) is connected securely in any suitabl'emanner with and is carried by the lens support 14 (Fig. 1) passing upwardly as shown (the encasing cable tube being rigid on the said support) and being curved forward and over as at 154. (Figs. 1 and 21), the cable 155 thereof having a loop portion 156 adapted to engage movably and by a pin indicated at 157 slidable in said loop with the shutter setting device therein shown. T he said slot and pin arrangementpermits the operation of the shutter independent of the cable connectedtherewith. The spring that returns the shutter device to normal position returns the cable 155 and its button 153 to normal position -b the spring action of the shutter device, w ich will be described later on. The other cable tube 158 and its cable 160 connects with the button 159 governing the diaphragmapertures or stops at one end and with the lever 41 of the lens support at the' other end-#the cable tube 158 connecting in any suitable manner with the lens support as indicated in Figs. 1 and 21, in which it is connected with a horizontally disposed tube 161 into which is led the cable 160. An elongated opening 162 is formed in the side of said tube, and a pin 163 (seevFig. 21)

connects a link 164.with said cable, the said link connecting at 165 with the lever 41. The indications and catch positions shown on the shutter scale of the cable settingP dey and the diaphragm indications lcarried by the -lens barrel indicated in Figs. 1 and 17. As

it is necessary that the shutter, diaphragm, andfocal step plateshall return4 to normal position i.- e. to T, 128 or 64, and tti-100 ft.' respectively when the camera is closed, so,

ya5 A and in a mannerthat, they may be reset to v new indications lbefore again' opening,.`or\

after opening the camera, it is necessary to provide a` strip or normalizing device to* effect such result. To effect this I employ the Vaction of the ordinary slotted side 1 bracket 166 common in folding cameras, the

same being pivotedatf167 to the (camera casing and at 168 yto the folding bed or door 3 feo y yvhich the actuating in the usual manner. Pivoted above the brackets 166'at 170 are levers J169, which are cleared around the pins 167 of the brackets and are provided with lugs 171 extending freely. over the upper portion of the brackets 166. The lower ends of these levers are turned inwardly and upwardly as at 172, 173, and are provided with inclined edges 174, and points 175. A spring wire 176 secured to the camera casing in any suitable manner, passes through a hole at 177 in the foot of the lever 169, and exerts a tension to hold the latter in forward position.

On opposite sides of the carriage 9 are pivoted as shown at 178, 179, but in a suitable manner, spring pawls 180, 181, the interme-l diate portion 182 of the wire of which pawls loops around in front of the carriage and bears on the track 7, being held in normal position thereon by the light pressure of a spring 183, carried by the carriage (see Fig. 21). The action of this device has formed part of the subject matter of my U. S. Letters Patent No. 1,362,833 issued Dec. 21, 1920, and further description is not necessary except to say that the retarding of the camera front through action of the said awls 180, 181 on their respective levers 172,

orces back the said levers, trips thereby' the side brackets 166 from their pins 167 and upon the folding of the camera bed or front immediately releases the levers 169 and the side brackets so that their springs thereupon force them forward again to operative position. 1t will be noted that the shank 184 of the button 163 extends inwardly past the path of movement of the back edge 185 of the adjacent lever 169, the said edge being shaped at such an angle and length as to enga e said shank 184, at whatever index position its button may occupy along the scale 131, and to so orcefthe said button out of its engagement with engaging teeth or members during the backward or tripping motion of the said lever 169 duringthe closingl of the camera front or bed, thus allowing the spring 116 (Fig. 21) to return the said button and -cable to normal position, and to again free the path of movement of the shanklof said button to permit of its immediate resetting-,as the back edge of the lever 169 clears away-from the said buttons shank. "\Fig. 27 shows a lever pivoted to the camera casing at 186, and having an arm 187 extending in the path of the front side, the shank of button 153, and a longer arm 188 having an edge extending in the path of the front side of the shank of button 159 and having a pin or lug 189 projecting across an`d back of the curved out portion of lever 169 to receive the action from tlie movement VVof said lever, in the manner pertaining to the button 136. A direct thrust form lofhy actuating devicev is shown in Fig. 28, in

lever 51, carried by the carriage 9, is modified in the form of a bellcrank 190, 191, in which the continuation of the pin or roller 52 projects u wardly, as in the action formerly describe to extend into the slot 680i the part 67 of cross bar 48 (Fig. 24). The arm 191. carries the pin or roller marked 192 that `projects downwardly and is adapted to imlginge upon and be moved bythe second mem er 193 pivoted at 194 to the camera bed, (Fig. 2,4). A limit pin 195 is placedy in the camera bed, out of the path of travel of the pin or roller 196, the latter being adapted to be secured to and de end from the carriage 9 into the ath of tie edge 197 of the member 193.

he step or cam surface given to the arm of member 193 at 198, 199 is for the purpose of the roller 196, forcing the member away, in order to impart increased movement where desired to the arm 200 thereof, and

to the bell crank V190, 191 to impart proper and easy motion to the lever 41, 42. 201 represents a cam plate the inclined edge 202 of which is adapted to force over slightly to the left the roller 52 of lever 51,to impart a short opposite movement to the 'lever 41, 42, or 74-75 to that imparted by the cam plate 71. Said cam plate 201 is secured as by rivets 203 securely to the camera casing. The effect 'of this cam will be afterwards explained.

The shutter and diaphragm setting mechanism pertaining to the lens and diaphragm tube or barrel is as follows: Figs. 5 and 7 show the front or cap plate 204 and front lens tube 205 removed from the shutter barrel 206 exposingl the diaphragm and shutter control device actuating cam plate 107, Fig. .7 shows a somewhat modified form of cam plate 207 and mechanism coacting therewith.

Projecting from the back of thel cap plate 204 is a tube 208. The cam plate 207 fits operativel said plate as at 213, and again parallel with the said face as at 214, and supports a pin or roller 215v on the under side thereof. This pin or roller is acted u on by the uper part 42 of the vlever 41 igs. 1 16) or 1s in constant engagement with the slot 216 of the lever 74-75 as in Fig. 18, the movement of said lever4 serving to oscillate the said cam late 207 to the various positions the lever is actuated toby the steps 72 of over the tube 208, the edge of. 4hole 209 ormed centrally in the said cam the actuating cam 71, corresponding to the various positions and indications of the diaphragm aperture index scale 64, 32, 16, 16+, 8, 8+, `4and 4+. A portion ot' the extension of the `said cam plate 207 is formed into 'a tooth or into two oppositely opposed teeth 217 (Figs. 1, 5, 7, 9,14, 16 and 18), the said tooth extending beyond the portion 213 of the cam plate 207. Lugs 218 and 219 project'upwardly from the cani plate 207 reely through concentric slots 220 and 221 res ectively, formed in the cap plate 204, and) freely through concentric slots 222 and 223 formed in a ring 224 which is preferably dished in on the under side as indicated at 224+ (see Fig. 16)` to receive between its under surface and the cap plate 204 a coil spring 225, whichv spring at 226 engages said ring 224 and`at 227 engages lug 219, the spring exerting a` tension to keepthe ring 224 in a ii'ghthand normal position. A pin 228'securedy to di. hragm lever 231 projects outwardly and reely through a concentric slot 229+ formed through the cam plate 207 (Fig. 14) and through the concentric slot 229 formed in the cap plate 204 and engages detachably in recess S or )V in the diaphragm controlling ring 224. liii 228 Vby its connection with the diaphragm, Kserves as an auxiliary diaphragmv setting means, whereby when pin 228 is in recess S the opening of the diaphragm will be suitable tor summer, and when pin 228 is placed in recess W the size of the diaphragm f opening will thereb be increased, as for winter light, and wil remain so lixed during automatic setting of the diaphragm until the pin isagain laced in recess S for automatic setting of t e diaphragm at decreased size opening thereof. A. knob 228x on ter (Fig. 16). It will be understood that when the ring 224 is oscillated its pin 228 by reason of engagement with the end of the diaphragm lever 230 (diaphragm indicated at 23,1) will'cause the enlarging anddiminishing of the diaphragm opening. 231 is an extension of the riig 224, which projects out over the dia hragm barrel 206 cup or box sha e232, the sidesof whiclibox 232 are cle awa as at 233 (Fig. 416)'to allow freepassage f the tooth or teeth 21.7 /bf the cam plate 207.A ,A cross pin 234 in said box pivots a lever-235 which leveris centered. in said box by .said .pivot and' passes freely through a narrow slot 236 and aeross the path of the movement of the cam tooth or teeth 2 17 to engage and disengage the latter, the slot 236 serving as a retainer o and guide to the movement of .the said lever.

The heel of the lever at 237 is formed in to a Y lug and a-spring 238 is shaped and secured as shown at 239. When the said lever 235 i's i,moved in and out by its free end, the heel pin 228 facilitates operation of the lat-r and is -formed downwarl y preferably in av 237 thereof will ride on either side of the projection 240 of the spring 238 and hold the levei' in such position. A similar extenvend of said spring entering the box 242 and having a bearing as at 251 against the left side thereof to assist the usual shutter tension spring to assure the return of the so formed shutter control lever 247 to its normal lcfthand position. In Figs. 1 and 5, it will be seen that a graded series of cani steps are formed on a portion of the outer edge of the cam. plate 207, as indicated at. 128, 64, 32, 16, 16+, s, 8+, 4 :ma 4+. These cam steps glide into one another and their determining .surfaces are disposed a distance apart radially, corresponding to the .radial distances apart of the index numbers Vo1 the diaphragm index scale indicated b v the like numbers located atthe bottom ot' the barrel 206, Fig. 1, and at the bottom of t-lie index scale plate of Figs. 17 and 18 (Fig. 18 omitting #128 of said scale). The

difference of the. circumferential diameter of the cam at the various steps corresponds to anddetermines the amount vof motion to be imparted to the shutter controlling lever 241-247. f i

1n operative connection with the atore said steps of the cam plate 207', a thiii lever 252 is pivoted as lat 253 to the obverse pin or roller 254, a portion ot said lever normally having a bearing on the lens tube 208, the upper end of said lever at 256 ending in a tpoth comprising a straight edge 2557 .and an inclined edge 258. A spring 259 attached to-tlie' cap plate v204 or to the barrel 206 as vat 260 exerts a tension on a .side of the cap plate 204, and supports a scribed upon the roller 254, -will move the lever 252 so as to set the shutter controlling vlever to the'vaijious speed positions. Extending as from the lever 241-247 in Fig. 5 is shown an arm 264 to which is pivoted at v265 a link 266, which at its lower end at 267 is pivoted to the cam plate 207. This lnierely shows a substitute form by which if the shutter lever 241-247 is moved to position by hand the cam plate 207 'will be thereby operated to set the diaphragm and the focal plate` devices to the various pos1" ment with each other when the lens front is ill raised or lowered or side shifted. To effect this result, I provide cam plate 207 with a series of ratchetteeth 268 corresponding in number radially with the number and the distances apart of the actuating 4cam steps 128 to 4+. A pawl 269 formed of a piece of light sprin Wire is journaled freely to the inside of t e barrel 206 as indicated at 270., .The end 269 of said pawl is adapted when moved inwardly to engagel the teeth 268, such engagement and the disengagement with said teeth bein effected by reason of the outer end 271 o the Wire constituting said pawl 269 gliding into and out of a recess having inclined plane surfaces 272, formed in the upright 13 of the lens supporting device. In Fig. 4 is seen a spring 273 attached to the back of the lens support 14, and bearing upon the end 271 of said pawl to normally keep its end 269 out of engagement with the teeth 268 except as the said support 14 is moved out of normal position. On the hack ot' the barrel is placed a wire `coil spring 274 (Figs. 9 vand 16) which is connected in any suitable way as at 275 with the back part of the barrelY 206, its outer end 276 engaging the extension 214 of thecam plate 207 by means of entering a hole 277 as in Fig. 9, or b means of a pin 278 as in'Fig. 16. The tenslon of this spring tends to return the cam plate to normal position upon the return of the lever 41--42 or 74--7 5 to normal position upon the retardingof the lens support or the closingof the camera.

In Figs. 7 and 8 is illustrated a modified form of cam plate and shutter regulating action in which' the lever 252v .is provided with a lug 288 which overlaps the cam plate 207 and is adapted to be forced into Contact witlrthe steps thereof when .the ordinary-, finger shutter trip llever 263fis depressed before theshutter is actuated, by reason-otl a spring 289 coiled around .the pivot 290 of theleve 263, and engaging with said lever 4at neend as indicated at 291, and having a "bearing on the under side of"a lug or pin 292 carried by an extending portion 293' which overlaps `the cam vplate and extends `downwardly on the obverse side thereof, as

shown. The spring 259 secured t'o the barrel Y206,;bears as upon .a portion of the lever 25' return. it' to normal position. In this "action the spring 259 should be weakerA 'than' the actuating spring 289.

From the surface offthe cap plate -204two y pairs of posts 294, 295 project and fitted to said four posts at the outer ends thereof is the shutter and diaphragm index plate 296 as shown in Figs. 17 or 18. The top edge of this plate is notched as at 297 to receive the lever 244, connected with the shutter regulating lever 241--247 to hold the said lever in either of the shutter regulating positions indica-ted bythe index designations placed adjacent the notches'. The lower edge vof this plate is notched as at 298 to receive in the various diaphragm aperture positions indicated opposite such notches the lever 235 of the extension 231 of the ring 224 connecting with and operating the diaphragm controlling lever indicated at 230. The slots referred to may be either straight recesses as shown or in the shape of ratchet teeth as indicated in Figs. 1, 5, 7, 11 and 12, and the dotted recesses representing the plus index setting positions may be dispensed; and' likewise the corresponding plus steps of the cam207 may be dispensed. The levers 235 and 244 may stand out of engagement with the recesses 297 and 298 of the index plate 296, except when forced forward and into said recesses by hand, but if the ratchet teeth recesses are employed, then the coil .spring 297 which bears upon the box 242 at 299, and upon the lever 244 as at 298, causes the said lever to remain in engagement with the ratchet teeth of the index plate until forced out of engagement therewith. The construction for accomplishing such result is as follows: Two thin plates 300 and 301 are provided with guide slots 302, 303 and 304, 305 adapted to fit over the four posts 294- 295. Clearance slots 306, 307 in said plate allow free passage of the lugs 218, 219, and clearance slots 308, 309 to allow theV passage of said lugs are formed in said plates. The top edge 310 of plate 300 extends upto the base of the recesses or teeth 29.7, and the bottom edge of said plate is cleared away as at 311 from the teeth on recess 289 ofthe index plate.y In plate 301 the top edge 312 is cleared away from the recess or teeth' 297 and the bottom edge 313 'is extended to the base of the said'teeth or recess 298 of the said index plate 296.y It is obvious that if the cani plate207 is oscillated .in one direc# tion, its lugs 218, 219 will move through the concentric slots of the plates 300, 301 with- -out affecting the relative position of said goncentrioslots force the themv to slide the required distance apart at A their outer edges toforce the levers224 and 235vout of the recesses or teeth 297 and 298 and so permitsby their respective spring actions, the return to normal position of the` aforesaid respective shutter and diaphragm controlling levers. The plates 300 and 301 are, of course, interposed between the ring 224 and the index plate 296. lt will be understoodl that the levers 224 and 235 may at will be moved by hand also to any desired index position either ahead or back of the position to which it may be automatically moved by the drawing out of the lens sup port and carriage, by simply drawing the A saidC levers back far enough from the recesses of the index plate 296 to not only escape the same, but far enough to escape the tooth or teeth 217 of the cam plate 207, and to escape the teethv 257 and 258 ofthe lever 252. When the Asaid cam plate returns to normal position the said teeth 217 and 257-258 will again engage their respeceo tive levers by forcing them outwardly temporarily and catching yback Iof them.' The action of the face 202 of the trip cam plate 201, Fig. 21, heretofore described, when the lens support is moved into the camera frame,

2:. causes, by the backward movement of the lever 41. 42 the tension of the returning spring 274, Fig. 9, and the spring 225, Fig. 13, to cause in the manner described the separation of the plates 300 and 301, totrip out of engagement the. levers 224 and 235, with respect to the construction shown in Fig. 1; but this back trip action with respect` to the construction shown in Fig. 18 is by the direct connection and pressure of the lever 74- a5 l75 instigated by thc said cani edge 202 of the plate 201. Another means of moving backwardly the cain` plate 207 to cause the separatingr trip motion of the plates 300 and 301, is shown in Figs. 1, 2`aiid 4, in which a i 40 lever 316 is attached to a stud 317 which at its otherl end is' attached to a lever' 318 "which in turn at 319 is connected with a link or bar 320, which bar'at its lower end passes through a guide hole at 321 of the base 45 cross piece 21 supporting the uprights 11 and ,13, the stud 319 being pivotally supported in extensions 322, 323 of the lens support 14. v`A normalizing coil spring 324 surrounds said stud 317 and is attached to the lensor .50 t0 said stud, and bears with its other end camera case 1, to ride up on an inclined surface 327, Figs. 1 and 21, of a spring trip lever 328, which is pivoted at 329 to the bottom of the casing 1. substantially-set forth in my said U. S. Letters Patent No. 1.362,833. When the rod 320 rides Iup on the 60., incline 327 of said lever, the end of the lever \316 is forced into the path of and up against the roller 215 of the extension 214 of the cam plate 207` and gives a backward motion to said cani plate to cause its lugs aspreviously desribed to expand the surfaces of aperture, and in general, except for moving objects, the shutter speed, so that if the lens support is brought forward tothe indication on the focal scale for 1.00 ft. and over, the

diaphragm will be set to the size aperture represented by the index number 16 therefor, and the shutter controlling levei will be moved forward to the index position 25 representing the position and tension for 1/25 second speed, and that consequently vas the #16 diaphragm aperture is the smallest one usually employed for snap shots, so the shutter speed isthe slowest used for snap shots. But 1/50I of a second many be made the normal slow speed for use with #16 diaphragm stop indication, if desired, by simply shaping the V first step of the cam plate 207 to cause the lever 252 to move the required greater distance. The other increased speed settings of the shutter will be proportional to the increased apertures given to the diaphragm. I prefer to cause the diaphragm regulator to move in the firstl instance to #16 stop position, and the sluitter regulator to 25, because 128, 64 and 32 of the diaphragm apertures and T and B of the shutter regulator pertain essentially to time exposures, and I provide the means in the construction shown to arbitrarily set by hand the regulators for such time conditions, and for any 'conditions and regulations that may be desired by the operator, different from lthose pertaining to ordinary amateur snap shot photography. i y

The term lens controlling devices hereinafter used means the diaphragm,.shutter and focussing means.
